Abstract

The current study was aimed to determine the effects of dietary supplementation with rumen-protected choline and methionine on dry matter intake, milk yield, milk composition and body condition score of transition cows. In this study, 32 Holstein dairy cows which made one parturition at least was used as the animal material. The cows were randomly assigned to four groups according to lactation number, previous lactation milk yield and body condition score before close-up. Cows within each group was fed a basal control (CON) diet (n=8). Cows in treatment group methionine (MET, n=8) were supplemented with 42 g/d of methionine (MetasmartR). Cows in treatment group choline (CHOL, n=8) were supplemented with 75 g/d of rumen protected choline (RPC) source (CholiPEARLTM). Cows in treatment group Mix (MIX, n=8) were supplemented with 75 g/d RPC and 42 g/d methionine. Milk yields and dry matter intakes were determined during the trial as daily. At the results of analyses that were detected; milk yield and composition the highest level in MET group (P<0.028). In conclusion of this study that was determined; the supplementation of methionine to the rations of dairy cows affected milk yield and composition positively

Özet

Bu çalışma, geçiş dönemindeki süt sığırlarında, rasyonlarına ilave edilen korunmuş kolin ve metiyoninin, kuru madde tüketimi, süt verimi, süt kompozisyonu ve vücut kondisyon skoru üzerine etkilerini değerlendirmek amacıyla yapıldı. Çalışmada, en az bir doğum yapmış 32 adet Holştayn inek kullanıldı. İnekler, laktasyon sayısı, önceki süt verimi ve geç kuru dönem öncesindeki kondisyon skorlarına göre rastgele dört gruba ayrıldı. Bütün gruplardaki inekler bazal kontrol rasyonu ile beslendi. Metiyonin grubundaki ineklere günlük 42 g metiyonin ilave edildi. Kolin grubundaki ineklere günlük 75 g korunmuş kolin ilave edildi. Miks grubundaki ineklere günlük 75 g korunmuş kolin ve 42 g metiyonin ilave edildi. Süt verimleri ve kuru madde tüketimleri günlük belirlendi. Yapılan analizler sonucunda süt verimi ve süt bileşenlerinin MET grubunda en yüksek düzeyde olduğu tespit edilmiştir (P<0.028). Sonuç olarak, yüksek verimli süt sığırlarının rasyonlarına korunmuş metiyonin ilavesinin, süt verimi ve bileşenlerini olumlu yönde etkilediği belirlenmiştir
